I agree with Patrick. It would be far better if this use case was
handled by the workflow.
A solution could be to have 'maintainers prereleases', that is isolating
the prerelease builds in another location so that RE don't have to take
care of them. A special flag on 'gbs sr" should probably be added for
that, or alternatively a special target name, same as gerrit: gbs
submit-t sandbox/<user>/tizen_common would create a prerelease build
over tizen_common, but not visible by Tizen:Common REs.
The big problem I see with that idea is: who will take care of the cleanup ?

Usually, the opposite happens: something is broken because you didn't
add the right package in the group submission.
Anyway, the case you exposes may happen and should try to handle it too.

I have two ideas:
1) simply communicate with REs, because YOU know that there's something
wrong. This works reasonably well, and there's nothing to do (except
writing a few emails :))
2) try to enforce the things in the workflow:
Submitting multiple packages is a kind of atomic transaction: you want
to accept all packages or no package. If not all packages have been
added, the transaction is considered as open, and the only permitted
operation is to rollback (reject the submission).
So we should add an extra gbs operation to 'finalize': when the
maintainer 'commits' the submission (which means: 'I won't add any more
package to it'), then it could be accepted (if it builds/images are
good/tests are ok etc.).
If a RE tries to accept a non finalized group submission, (s)he should
get an error.
Well, that could work, but it's quite difficult to evaluate if your
initial problem deserves such added complexity.
